May subsequently be pickled or bright dipped but the rough surface remains. \nScratched Brushed Finish (Satin Finish) – Obtained by mechanically brushing with wire brushes or by buffing. \nFLAT WIRE\nNo.2 Finish – A regular bright finish. \nNo.3 Finish – Best Bright High Gloss Finish produced by use of polished rolls.
